There's this dot point in the generators section of M&G about assessing the competition between Edison and Westinghouse. I asked my teacher about this and he had no clue about it. Also it ain't in any textbooks i've looked at.
Any help?
A couple weeks ago, our teacher gave us this problem solving exercise as something to do between studying. It goes like this:
Predict what would happen to the colour of the sun if it suddenly shrank in size? Why?
I've done a bit of research but can't find anything conclusive.
Any help...
